Textfield in Form

Jack2003

Hi,

Is there a way to load the content of a textfile into a formfield so the user can change it and then writes it back by submitting the form.

Thanks in advance,
Jack

The following gets the job done, its a) not secure, b) a little redundant.

So you can clean it up as you see fit.

Also, Im not the greatest with Java Script so the :

if(file_exists("$filename")) {
echo "<script>result = confirm(\"Overwrite current '$filename'?\");
if(!result) history.go(-1);</script>";
}

code works, but if the user hits cancel, they get taken back one page, but the file still saves.. so perhaps a simple "die;" somewhere will solve that, im not sure though..

to open a file with the editor.. itd be editfile.php?file=FILENAME.extension...
I.E. you are trying to edit menulayout.php

http://ursite.com/editfile.php?file=menulayout.php


<? 
global $PHP_SELF, $submit, $filename;


function save_file() {
	global $filename, $filebody, $PHP_SELF;

if(file_exists("$filename")) {
echo "<script>result = confirm(\"Overwrite current '$filename'?\");
if(!result) history.go(-1);</script>";
}

if($file = fopen("$filename", "w")) {
	fputs($file, $filebody);
	fclose($file);
	echo "Filed saved successfully!";
}

else {
	echo "Sorry, there was an error saving the file '$filename.'";
     }


}


$file = $_GET['file'];
$filename = $file;
$submit = $_POST['submit'];

// Make sure they aren't trying to edit this page or the 'create new file' page.

if ($file == "editfile.php" || $file == "newfile.php") {
	die ("Sorry, you cannot edit '$file'!");
	}


if($file = fopen("$filename", "r")) {
	$filebody = implode("", file($filename));
	$filebody = htmlspecialchars($filebody);

fclose($file);
}

// If Form was submitted
if ($submit == "Edit File!") {
	$filebody = $_POST['file'];
	$filename = $_POST['filename'];

if(!empty($filebody) && !empty($filename)) { // If there is content and a filename


save_file();

}
else { // if they are missing either content or a file name
echo "There was an error saving the file!";
}
}
?>
